def one_run(evaluator, config, frequencies):
'''
Performs a single run of the given configuration. Returns a dictionary
containing results.
Parameters:
- ``evaluator``: An object with the function get_fitness that takes an
individual and returns its fitness value
- ``config``: A dictionary containing all of the configuration information
required to perform a experimental run, including:
- All information required to initialize an individual.
- All information required to run ``evolution.generate``.
- ``verbose``: Boolean value for if extra runtime information should
be displayed.
- ``max_evals``: The maximum number of evaluations allowed before
termination.
- ``max_fitness``: The fitness required to cause a "successful"
termination.
- ``frequencies``: Dictionary used to return information about how often
individuals of different lengths are evolved.
